Specification of Letters Patent.

Serial No. 637,953.

To (All whom it may concern.

Be, it known that I, LESLIE M. SHERIDAN. a citizen of the United States,residing at Anaconda. in the county of Deerlodge and State of Montana.have invented a new and useful Ore-Sampling Device, of which thefollowing is a specification.

This invention relates to improvements in ore sampling devices. and theprimary object of the invention is the provision of an ore samplingmeans adapted to be disposed between the spout of an elevating apparatusor delivering hopper provided with a receiving hopper having a samplingdischarge and an ore discharge, with means interposed therebet-wecn forintermittently permitting the ore to enter the sampling discharge andduring other period of time to cause the ore to tlow in the. regular oredischarge into the proper concentrating or amalgamating apparatns,

A further object of the invention is the provision of a novel structureof what is termed ore cutter disposed for sampling ore and operablyconnected by a peculiar form of cam whereby said cutter is operated topermit the ore to How for the greater length of time to the proper oredischarge and at intermittent periods and for a short period of time toconduct a sample from the main ore flow to the sample discharge. thusproducing a cutter of very simple construction and of few wearing parts,and so timing the same as to produce the desired result.

A still further object of this invention is the provision of a novelform of receiving hopper having a sample discharge and what is termed arejection discharge in combination with an oscillatory ore cutterdisposed above the said hopper and operably connect d with a cam devicefor disposing the same with relation to the discharge spout of an orehopper so that the ore is permitted to flow at the desired time into thesample dis charge spout or to the rejecting discharge spout.

Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed. it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without dcparting from the spirit of the invention.

in the drawings Figure 1 a side elevation of the complete device, dottedlines illustrating the position of the cutter and cam and permitting theore to be discharged in the sample spout. Fig. 2 is a top plan view ofthe invention showing the support ing frame. Fig. 3 is an elevationtaken from the upper end of the apparatus, the sampling hopper beingshown in cross section with the cutter discharging into the rejectiondischarge of the apparatus. Fig. 4 is a detailed perspective view of thecutter removed. Fig. 5 is a detailed view showing the rocking arm androller for engaging the cam to operate the cutter.

Referring to the drawings. the numeral 1 designates the elevator hopperor tunnel or in fact any device which is adapted to receive the ore andconvey it for sampling and concentration or amalgamation the same beingprovided with the discharge spout 2. which empties into and above thereceiving hopper 23. This receiving hopper as clearly shown is providedwith the central curved partition wall 4 which divides the hopper intothe main receptacle 5 and the sample receptacle 6, the main receptaclebeing provided with the discharge spout 7 while the sample receptaclehopper is provided with the discharge spout 8. the said discharge spoutsbeing disposed. as shown in Fig l at oppositely disposed angles. forconveying the ore in the desired direction and place for concentrationand amalgamation or for sampling.

The main framework as clearly shown has disposed therein the transverseshaft 10. and upon its end near the hopper is a sleeve or collar 11.carrying the integral depending lug or connecting arm 12. for thedetachable reception of the lug 13 of the cutter or deflecting spout 14.which is provided with the two inwardly inclined triangular shaped walls15, which cause the cutter to be a chute or spout to normally be heldbelow the lower end of the spout 2 and convey the. greater portion ofthe ore therethrongh into the receptacle 5 and through the spout T.

Mounted upon and adapted to rock with the shaft 10 at the opposite endfrom the collar 11 is a crank arm 16. provided with a pin 17. whichpivotally connects the said crank arm to the pitman or connecting rod18, whose other terminal is pivotally mounted upon the pin it) carriedin the lower free end of the oscillatory arm or link 20, whose upper endis pivotally connected upon the shaft in the brackets 21 as clearlyshown in Figs. 1 and 2. It will thus be seen that the said arm or link20 when being rocked or reciprocated will impart to the cutter l t amovement to cause the same to assume the position as shown in full anddotted lines in Fig. t. In order to actuate the said link 20 and the rod19 and consequently the cutter 14 as desired, upon the inner end of thepin 19 is mounted an antifrictional roller 32, which normally moveswithin the cam groove of the cam 23, the said groove 24 being providedwith the small inner concentric portion It and the enlarged outerconcentric portion 7), the inner portion of the cam 23, holding thecutter 1-1- in the position as shown in full lines in Fig. 1 but whenthe said roller 22 is in engagement with the portion of the cam at 1),the said cutter 14 will assume the position as shown in dotted lines inFig. l and therefore permit the flow of the ore to the spout 8 notdeflecting the same into the spout 7. The cam '23 is keyed upon theouter end of the shaft 25, which is mounted in the frame 9 and isoperated by the fast and loose pulleys 26 as clearly shown.

From the foregoing description it is evident that the cam may be soconstructed to time the operation of the cutter or chute it so that thedesired sampling of the ore will be accomplished momentarily and at thedesired time the quantity taken for a sample being determined by suchtiming and not interfering in the least with the discharge of the orefrom the elevator hopper or other source. It will also be seen that thehopper is disposed to convey the ore to the spout T and is not employedto convey the ore to the spout 8, the same being mounted above thecompartment 6 and when in operable relation with the spout 2 will at alltimes convey the ore to the compartment or receptacle 5 and the spout 7,and when in the position for sampling will be from below the spout 2 topermit access of the ore to the spent 8 of the compartment or receptacle6. By this means the wear upon the spout is greatly reduced and even incase where the same needs replacing, it is simply necessary to detach itfrom the arm 12 and replace it with a new one.

What is claimed is 1. The combination with an ore supply hopper and asampling hopper divided longitudinally by a partition having a curvedupper edge and having two oppositely inclincd spouts, one upon each sideof said partition, of a frame, a power shaft journaled therein, a camrotatable with said shaft, a link pivoted at one end to a fixed pivotand having its free end in engagement with the cam, a rod pivoted to thefree end of the link, a rock shaft journaled in said frame. a crank armcarried at one end thereof and operably connected with said rod, aconnecting arm carried upon said rock shaft at the opposite end to thecrank and depending above one side of the hopper, and a cutter carriedby said connecting arm and disposed for oscillation within the hopperabove the partition and between the spouts and the supply.

2. The combination with an ore supply hopper and a sampling hopperdivided longitudinally by a partition having a curved upper edge andhaving two oppositely inclined spouts, one upon each side of saidpartition, of a frame, a power shaft journaled therein, a cam rotatablewith said shaft, a link pivoted at one end to a fixed pivot and havingits free end in engagement with the cam, a rod pivoted to the free endof the link, a rock shaft journaled in said frame. a crank arm carriedat one end thereof and operably connected with said rod, a connectingarm carried upon said rock shaft at the opposite end to the crank anddepending above one side of the hopper, and a cut ter connected to theconnecting arm, said cutter having an inclined chute and two inwardlyinclined walls, the lower edge of the cutter projecting beyond and belowthe curved upper edge of the partition of the hopper and describing anarc of a circle to conform to the curved upper edge of the partitionwhen reciprocated.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

LESLIE M. SHERIDAN.
